Commande tm._uac_start JsonRPC with Headers From, To and Fake works {"id":1,"jsonrpc":"2.0","method":"tm.t_uac_start","params":["REGISTER","sip:suio.com","sip:101.155.139.171:5060","udp:10.155.139.170:5064","From:sip:juan@sui.com\r\nTo:sip:juan@sui.com\r\nFake:hedear\r\n"]}

{ "jsonrpc": "2.0", "result": { }, "id": 1 }

But commande tm.t_uac_start JsonRPC with only Headers From and To doesn't works

{"id":1,"jsonrpc":"2.0","method":"tm.t_uac_start","params":["REGISTER","sip:suio.com","sip:101.155.139.171:5060","udp:10.155.139.170:5064","From:sip:juan@sui.com\r\nTo:sip:juan@sui.com\r\n"]}

{ "jsonrpc": "2.0", "error": { "code": 500, "message": "out of memory" }, "id": 1 }

On documentation module tm, only From and To headers are mandatories.
